Root canal treatment is a precise dental operation that should be properly performed for endodontic success and survival. It is known that the endodontically treated teeth have lower fracture strength than vital teeth. If cracking exists in the endodontically treated tooth, the fracture strength of the tooth is more decreased, so proper management and treatment are required for success and survival of this tooth. This study aimed to declare the affecting factors and the degree of success and survival of endodontically cracked teeth. In this review, a MEDLINE search was completed for the time period from 1990 to 2019 along with a manual search, to locate relevant peer-reviewed articles and textbooks published in English. Several keywords were used to obtain all possible articles concerned with the subject. We found 25 articles on our search, out of them, only 21 articles were specifically related to our subject. This review concluded that few studies have focused on studying the degree of success and survival of endodontically cracked teeth and most of them were trials. Also, there were no previous review articles studied on this subject.
Key words: Cracked teeth, success, survival, endodontic, radicular extension.
